Be it known vthat I, JOHN B. CLERMONT',

'of New Yorkin,the county of Bronx and in the 'State of New York, have inventeda certain new and, useful Improvement 1n Apparatus andPackage forj- Ifo'rming Solutions by Percolation, Aand do `,hereby' declare that the following vis ajfl'lll.clear,4 and exact description thereof. 1 u The object of-myti vention' has been to provide an apparatus ,'forQforming' solu- A `Th't of great simplicity.; that-of 'A infusions to be v,I`nade`of -such substances as coffee by passin the water or other liquid. I that ofenablingthe material being leached tions by percolation, and a package of material for use in such apparatus, whlch shall be adapted, among lother` uses,- for use in` making .cofl'ee, and which shall have any or allof the following advantages:

My invention is 4.capi'able use" for-,many different purposes,A and z in many dii'erentA forms; and while I have chosen for illustrating lit the best e1nbodiment of my per-l colating apparatus *whichis known to me,v

such apparatus and package for'use therewith are to be regarded as only one ofmany.

Specification of Letters Patent# Patented May-.'10, v1921 l Thgiuuarad,embodiment efmy' 'inepg y tion 1s adaptedrparticularly for the manufacture of coffee. In such embodiment,fI

have shown a base 1 whichis4 adapted to lit over-a `cu `2 or other vessel .into -which the made co eejisto drop, .such covery havits .escapingfromoif/the cup. In the center of t onor attached tothe. base, andwhich, in

e base sleeve 3 which isk formed the; present instanceVcarries a tube 3F' that'.4 i

l has an `inturnediiange 4 yat its lower edge.` A pot .orbo'dy isl rovidedfwith a neck 6I that 1s adaptedto' t thefsle'eve 3, in the present instance fitting the outside of the sleeve. [A bayonet .jointfisformed between the' sleeveand the neck byw'pins 8 4on -theY lsleeve, adagted toengage cam. slots 9 in the neck. y cover V1Q is provided for clos- I ing the vupperend o'f` i', l1`epot.vI In `'the presi `main therein ,in thefform. of a package so ,as to provide not only for simplicity of operation,` but for easily cleansing the` apent zembodlment of my invention I `provide a bottomfllwhich closesgthe lower.v end of o the pot5 except that attached t othe bottom is a` preferably conical?,nozzle 12, which is which isv erforated. l

the .infusion lis to be formed is provided iin such'` packages preferabl having substanthrough substantially the whole;4 layer of dandfthe `Wall of l ed tobe received-within and tomake a sub- .v'stantlally' water-tight` connection with they pot, 4and preferably with the neck of the,pot,

solid materialfrom" which the infusion is4 to f be made. I referto makef-thevertical walls 1 metal,` orsized paper, but itis obvious that rial which will permit the passage ofthe water or otheriliquid while `preventingthe may be formedof unsized ting ,'paper. The materia forming the shoulder 14 is preferably turned over escapeof the solid material,y and such disk i aperlike blotl yderneath thedisk to secureit in place. I'

-k pass througrthe coffee 1 .15

preferably Y'make' the to 16 of thepackage ,suiicientlyg's'ti'h as by" orming it up 1n one piece with the material of the side walls 13' of the package, so that, the .supported by the flange 4, an

,package being ing properly,- proportioned, they engagement ofthe bayonet joint shall so force the nozzle into `an opening 16a in the top l16 and into firm contact with allip or flange 16b extending aroundvthe same as to make a substan- -tially water-tight joint therewith and compel all water going throu h the nozzle to and the filter paperk 15. oth the upper land lower ends @of the cartridge may be sealed as by seals 18r and 19 formed,'for instance, of paralin I tissue paper, and which are easilytorn off.

'Inthe use of my apparatus and cartridge, the cartridge, loaded with pulverized coffee,

3 isl made ready for use by tearing olf the thin yseals 18 and 119, and is placed on the .flange f 4 of the :cover 1. lThe neck 6 is'thenplaced kr.lover .thev sleeve and by means of the bayonet joint isl caused 'to force' the nozzle 'tightly into the hole in the top of the package and to clamp the shoulder 14 against the flange-1,' so as to make a substantially water-tighty joint.' The pot is sup orted' upon the cup or other receptacle whic is to receive the coffee extract, and the required amount ofV water is poured into the pot throughits top. The perforated nozzle not .onlyy sprays the water substantially evenly throughl the cofee, but it allows the air in the packagel to'esca e and so .presents the water to t e masso coffee grains that it is enabled to penetrate thelatter, and the formation of a sulicient skin effect at the perforations to prevent the escape of the air, is prevented. The vpoint -on the nozzle also enablesthe nozzle to be forced through the vsealingdisk l18, if desired, without removin the latter.` The waterenters the nozzle an by its perforationsis sprayed laterallyon through thev coffee, and as it can only enter through the perforations yofthe nozzleand can only `escapethrough the porous paper disk,' all thefwater'is compelled to pass entirely through the layer of coffee and is al1 i thussubstantially e ually presented tothe pulverized coll'ee.- he result is that the wateris in contact with coffee long enough to take up itsbenecial extracts but is not in contact longenough to dissolve its harmful ingredients.v `In this f way, although the water may pass but once through the ground` v coffee, fluid coffee of the linest flavor ma be obtained and with theleast amount of terious substances thereinyand it is found j that substantially all of thebeneficial materials in the coffee can be extracted with the single passage yfof the water therethrough.

It will be seen that my apparatus and the parts beelecartridge' have, amon others, the following advantages in addltion to those just described:

'The use ofthe cartrid e enables the material being leachedto e introduced into the apparatus and removed therefrom without ever losing control of the material, the

used coffee grounds being perfectly removed by simply removing the package. Thus not fonly is the operation of charging and emptying the percolator performed with great simplicity and cleanliness, but an infusionv is obtained of the greatest possible strength, and all the material'. being 'leached is insured of 'thorough and equal treatment by the water or other liquid. Regulating the size of the cartridge isa convenient and accurate means,` 4for y measuring the proper amount of co'e'e or other material to vform the desired quantity of the infusion. The apparatus is of great simplicity and can be usedv out of `dorms,without other facilities than those for ,supplying hot water.

^ It is ,obvious that various changes can be made in the above-'described embodiment of my invention which would be within the scope of the invention. For instance, the

j cartridges may be charged with more lthan a sin le substance, such, for example, as with co ee and milk l in a dried form, as well as su ari claim: j
